Flat Idler Pulley
The internal bearings in the flat idler pulley often seize or develop flat spots. When the pulley fails to rotate at the same surface speed as the belt, it creates a high-friction interface that rapidly overheats the rubber compound, leading to catastrophic belt failure.

V-Idler Pulley
This pulley maintains alignment within the V-groove of the belt; if the bearing wobbles or seizes, it forces the belt to 'climb' out of the groove. This misalignment causes the belt to rub against metal belt guards or guides, shredding the outer wrap and snapping the belt.

Deck Drive Belt
The belt is the component experiencing the ultimate failure. A genuine OEM replacement is required to match the specific cord-angle and length requirements of the Timecutter SS4225 deck, as 'will-fit' belts often have slight dimension variances that cause them to jump off the pulleys.
